So I lost a spring. Yup. I'm that DA who failed to keep an eye on her workspace and then got up and went outside. Guessing it took a hike.
I hyjacked every pen in the house and hilariously one from my work has saved me.
Got it all reassembled and linkages exact just from memory and where each made sense. They all check out from the SOR photo.

Yeah huh. Still fighting off choke idle issues. Lowest I've ever ever seen her tho... w/ the tiniest bit choke she's idling at 665 but fluctuates up to 720 (timing gun attached). Timing set at the bb for now. Vac gauge fluctuates from 18-15. IM out 3.5 turns. I tried to go to 3.75 and she started to sputter hard. Fuel in the sight glass is right in the middle. Clearly an air leak somewhere unless it's my compression and or poor valve adjustment.
Too annoyed right now to fuss more. When have more patience and less headache I'll plug most of the valves and go from there.

Getting close Felicity. Are you having the idle issues with a cold engine, or also when it's fully warmed up?

Warm. Hey two lovely things that are making me smile that are fully working now... my oil gauge and my carb fan.

Hang in there. I rebuilt two carbs exactly the same. One ran crappy and one runs puuurfect. I wish I knew how this works but it's still an unknown.

I'm starting to really think it's my valves... compression numbers weren't great. I got a mighty vac yesterday and in the first two pages of the manual it talks about different vac readings. Mines fits right into sticking valves. Will keep plotting forward but my gut is feeling tied up.

Bought myself a Mity-vac and found my driver side VCV shot... barely used by me, bought used from CP in NH. (they emailed back its warrentied) So for now all my evap lines are pulled or capped. And with the new toy I found my primary port on my distributor is shot. Secondary is good. So I need to advance the timing seeing as secondary is ~7 degrees. FSM shows 7 degrees BTDC @ max 950 rpms (w/ vac advance cut).

I have a timing gun but must be the few beers I had last night and not a ton of sleep or the blond roots... I'm very visual. So someone be a doll and draw me a pix? Or fill in the blanks on this one... bonus points as noted to the upper left for marking up my pix.

Been driving the truck for a few days... I tried the distilled water in the primary of the carb but going to try it again. First time around I just had the choke pulled to top for 2k RPMs but feeling like propping the gas pedal is what I should have done. Forgive me for not being 100% the difference it makes. I instilled 1/3 a gallon but saw nothing on a piece of cardboard I propped in front of the tailpipe (on the video you can see some brown spots but being here in the utterly invaded part of CT by gypsy moth caterpillars... that's just s***).



So for two days I have been driving it, she still wants to stall out at a quick stop but not at a stop pointing up. So starving for fuel is what I gather from that... During travel it has a hesitation with acceleration not too much different from when I first drove her and all this started to really bug me over a year ago. Difference I have ferom a year ago is "experience" under my belt and so all this s*** kinda makes a bit more sense.
ACC pump is the OEM leather... IF carb is out of truck or truck is sitting, will that leather need to be hydrated with oil @FJ40Jim? (I had just for the sake of it). Will leather tighten back up if it gets pulled out of shape? Seems it will as I had tweaked it out when I was putting the top on and off testing out my "MacGyver" pen spring a few weeks back for the throttle pump spring I lost.

Pulled the top off the carb last night because I had noticed my fuel in the sight window was way friggen high yesterday. ACC leather was smooth and tight. And at that time gave my ACC pump a push or two and saw the expected squirt of fuel so my spring definitely works. I found my float lower than the fsm spec of 6mm, reset it and now the level is a tad low.

So far I have my IM out 4.5 turns... and keep needing to refer to this till it becomes ingrained in my memory.
** More Choke = less air
** Idle Mix (IM) OUT = more fuel
** Pushing Choke IN means more air requiring more fuel

Have a paperclip setup under the vacuum diaphragm to see if the spring is even moving in there during WOT (wide open throttle). (a new diaphragm was replaced with a new rod when I rebuilt the carb).

Will also add that a few weeks back I noted a vac leak toward the firewall end of the manifold... ordered a remflex gasket but have yet to pull everything apart again. I just want to drive the f-ing truck. Looking at that gasket is like knowing doomsday is on the horizon for a parent who is single and busy with a 4 year old and works part time.

Personal day from work today.... being paid to chart this out on my thread. Bonus. Tho Mother Nature is a wench and its pouring out there so I can't go fiddle on the truck. Wedding picnic in a few hours if it clears as said by the radar.

Few pics for reference.

BB is 7 degrees advance, with vac lines disconnected and plugged. Straight line is TDC or 0 degrees.

Yes I get that. When I found that my inner port on my vac adv on the diz was blown I swapped the line for the outer and advanced the timing to about 10.
Last night I backed the timing off some and have since capped the vac adv on the carb. I also added a paper clip to the secondary diaphragm rod on the carb. Took it for a hard drive up and down the twin hills I live on and neither time in third and WOT or forth did it move so I'll be swapping out the spring on it. I'll say I noted the pop pop on decel and downshift to be far less since tweaking her back.

I am so dragging ass on pulling the manifolds again to swap the gasket w/ a remflex I picked up a few weeks back. I know I've got some leaks along that far right edge near the firewall. My son will be w/ his dad on the longest stretch ever, 10 days starting 7/7 to 7/17. I suppose that will be the time. Lots of swearing, a beer or two and many bloodied knuckles on the horizon. Woohoo. I know one of these days I'll be able to look back and see how far I've come but some days it just flat out pisses me off at how much work I've done and I'm still struggling.

Hang in there, F. You'll find that it will go MUCH fasted this time around. You know where everything goes, what order to remove and replace, and none of the bolts will be seized. It makes a huge difference.

I've done this so many times now, but I still always seem to forget something at the end. Here I am with my carb all bolted and torqued down. Just when I reached for the throttle linkage, I remembered that I forgot something

 

[NeverGiveUpYota]

Hehehehe Ryan! Thanks for the chuckle.
And yes G, agreed. I still hate that last bolt on the exhaust manifold horn. Even w/ smaller hands getting it snugged down just stinks.

 

[mattressking]

How much for the 3rd vac advance?

I did the same thing today too

I knew I couldn't have been the only one! haha
